[0017] Figure 3 It is a structural schematic diagram of an embodiment of a beverage preparation system. DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0019] In order to solve the problem of foreign matter being easily accumulated in the pipeline of the beverage preparation device in the related art, an embodiment of the present application provides a cleaning device that can be applied to beverage preparation devices, automatic cooking machines and other catering equipment. The following is a detailed description of the implementation method of the cleaning device applied to the beverage preparation device.

[0020] The detailed composition structure of the cleaning device is described below with examples.

[0021] See also Figure 1 , Figure 1 It is a schematic diagram of the structure of an embodiment of the cleaning device of the present application. It should be noted that the cleaning device in this embodiment can be applied to beverage preparation devices such as milk tea machines, juice machines, etc., and can also be applied to devices with pipeline conveying structures such as automatic food processors, coffee machines, dishwashers, etc., without limitation here. In this article, a beverage preparation device is used as an example and illustration of the device to be cleaned, and the application scenario of the cleaning device in this embodiment is not strictly limited.

[0022] In one embodiment, the cleaning device includes a housing 10 and a pipe assembly 30. The housing 10 includes a water containing chamber 11, and the water containing chamber 11 can store liquid such as water.

[0023] The pipeline assembly 30 has at least two sections of pipe groups. The at least two sections of pipe groups are connected between the water chamber 11 and the device to be cleaned, and the pipeline assembly 30 can selectively conduct the passage between the water chamber 11 and the device to be cleaned. The cleaning agent and / or the water in the water chamber 11 flows through one section of the pipe group, the device to be cleaned, the other section of the pipe group and the water chamber 11 in sequence, and circulates between the device to be cleaned and the water chamber 11 through the at least two sections of the pipe group.

[0024] As such, the cleaning device in this embodiment can allow the cleaning agent and / or water to circulate between the water holding chamber 11, the pipe assembly 30 and the device to be cleaned, thereby repeatedly flushing the pipes of the device to be cleaned, so as to improve the cleaning effect, and further reduce the foreign matter residue inside the device to be cleaned, which is beneficial to the cleanliness of the device to be cleaned.

[0025] Furthermore, the cleaning device may further include a storage assembly 20. Specifically, in one embodiment, the cleaning device includes a housing 10, a storage assembly 20 and a pipeline assembly 30.

[0026] The housing 10 includes a water containing chamber 11 , and the water containing chamber 11 can store liquid such as water.

[0027] The storage assembly 20 is disposed on the housing 10. The storage device is used to store at least one cleaning agent. The storage device includes at least one storage cavity 21, each storage cavity 21 stores a cleaning agent, and the cleaning agents stored in two storage cavities 21 are allowed to be the same, or multiple storage cavities 21 can store different cleaning agents, which is not limited here.

[0028] The storage chamber 21 has a discharge port 22 through which the cleaning agent is released.

[0029] The pipeline assembly 30 has at least two sections of pipe groups. At least two sections of pipe groups are connected between the water chamber 11 and the device to be cleaned, and the pipeline assembly 30 can selectively conduct the passage between the water chamber 11 and the device to be cleaned. In addition, the discharge port 22 is connected to the pipeline assembly 30, and the discharge port 22 can be directly connected to the pipeline assembly 30 or indirectly connected to the pipeline assembly 30, which is not limited here.

[0030] When the pipe assembly 30 opens the passage between the water chamber 11 and the device to be cleaned, the cleaning agent and the water in the water chamber 11 flow through one section of the pipe group, the device to be cleaned, the other section of the pipe group and the water chamber 11 in sequence, and circulates between the device to be cleaned and the water chamber 11 through at least two sections of the pipe group.

[0031] It can be seen that the cleaning device in this embodiment can circulate the cleaning agent and water between the water containing chamber 11, the pipe assembly 30 and the device to be cleaned, thereby repeatedly flushing the pipes of the device to be cleaned, so as to improve the cleaning effect, and further reduce the foreign matter residue inside the device to be cleaned, which is beneficial to the cleanliness of the device to be cleaned.

[0032] like Figure 1As shown in the example, the discharge port 22 is connected to the water chamber 11, and communicates with the pipe assembly 30 through the water chamber 11. In other words, the discharge port 22 is provided on the side of the storage chamber 21 facing the water chamber 11, and can release the cleaning agent to the water chamber 11. The cleaning agent flowing out of the storage chamber 21 can be mixed with the water in the water chamber 11, and then when the pipe assembly connects the passage between the water chamber 11 and the device to be cleaned, the cleaning agent and the water flow to the device to be cleaned through the pipe assembly 30 together, that is, the mixed liquid of the cleaning agent and the water circulates through the device to be cleaned and the water chamber 11 through the pipe assembly 30, which is conducive to the uniform mixing of the water flowing through the device to be cleaned and the cleaning agent, and can ensure the cleaning effect to improve the cleaning efficiency.

[0033] Please continue reading Figure 1 In one embodiment, at least one storage chamber 21 includes a first chamber 211 and a second chamber 212, which are used to store a descaling agent and a cleaning agent, respectively, so as to descale and clean the device to be cleaned.

[0034] Optionally, the discharge port 22 of the first chamber 211 can be controlled / manually adjusted to release the descaling agent, so that the mixed liquid of the descaling agent and water is continuously flushed in the device to be cleaned. After reaching a preset time or a preset number of times, the mixed liquid of the descaling agent and water in the cleaning device and the device to be cleaned is discharged.

[0035] Then, the discharge port 22 of the second chamber 212 can be controlled / manually adjusted to release the detergent, and water can be added to the water chamber 11. The mixed liquid of detergent and water is continuously flushed in the device to be cleaned, and after reaching the target time or target number of times, the mixed liquid of detergent and water in the cleaning device and the device to be cleaned is discharged. In this way, by first using a descaling agent to clean the scale of the device to be cleaned, and then cleaning it with a detergent, the risk of residual descaling agent can be reduced, which is conducive to improving the cleaning effect of the cleaning device.

[0036] Then, water may continue to be added into the water containing chamber 11 so that the water can be flushed in the device to be cleaned to clean the residual detergent.

[0037] In an alternative embodiment, the order of using the descaling agent, the detergent, and water can be adjusted. For example, the detergent is first used to clean the device to be cleaned, and then the descaling agent is used to descale the device to be cleaned; or, the device to be cleaned is first rinsed with water, and then the descaling agent and the detergent are used to clean the device to be cleaned in turn, and then the device to be cleaned is cleaned again with water, which will not be repeated here.

[0038] Please continue reading Figure 1 In one embodiment, the pipeline assembly 30 may include a first pipe group 31 , a drive group 32 , and a second pipe group 33 .

[0039] One end of the first tube group 31 and the second tube group 33 are both connected to the water chamber 11, and the other end is connected to the two ends of the pipeline to be cleaned of the device to be cleaned. Figure 1 The pipeline to be cleaned is indicated by a dotted line.

[0040] That is, one end of the first tube group 31 is connected to the water chamber 11, and the other end of the first tube group 31 is connected to one end of the pipeline to be cleaned. One end of the second tube group 33 is connected to the water chamber 11, and the other end of the second tube group 33 is connected to the other end of the pipeline to be cleaned.

[0041] The driving group 32 is disposed on the first tube group 31, and can provide power to allow the cleaning agent and water to flow to the pipeline to be cleaned through the second tube group 33, and flow back to the water containing chamber 11 through the first tube group 31. For example, the driving group 32 may include a water pump and / or a peristaltic pump, etc., which is not limited here.

[0042] That is to say, the driving group 32 can provide power to make the liquid (water or a mixture of water and cleaning agent) in the water containing chamber 11 flow to the second tube group 33, and then flow to the pipeline to be cleaned of the device to be cleaned through the second tube group 33. After the liquid flows out of the pipeline to be cleaned, it flows back to the water containing chamber 11 through the first tube group 31.

[0043] Please continue reading Figure 1 In one embodiment, the first tube set 31 may include a cluster interface 311 and a one-way valve.

[0044] The cluster interface 311 is used to connect with multiple pipelines to be cleaned of the device to be cleaned; wherein, the pipeline to be cleaned can be connected with another cluster interface. When the pipeline of the device to be cleaned needs to be cleaned, the cluster interface 311 can be docked with the cluster interface of the pipeline to be cleaned to achieve a quick connection of the pipeline to be cleaned of the device to be cleaned. When the cluster interface 311 is connected with multiple pipelines to be cleaned of the device to be cleaned, the control module can control the one-way valve to be turned on to allow the cleaning agent and water to flow to the pipeline to be cleaned through the cluster interface 311, thereby facilitating the reliable flow of the cleaning agent and water to the pipeline to be cleaned and reducing the occurrence of backflow of the cleaning agent and water.

[0045] That is to say, the number of pipelines in the first pipeline group 31 is less than the number of pipelines to be cleaned, which is conducive to simplifying the structure of the cleaning device. Figure 1 As shown in the example, the number of pipelines in the first pipeline group 31 can be one.

[0046] The driving group 32 includes at least one driving member M1, which is disposed on a side of the cluster interface 311 away from the pipeline to be cleaned, and can provide power to make water and cleaning agents flow to the first tube group 31 and flow to the pipeline to be cleaned through the cluster interface 311.

[0047] Optionally, the cluster interface 311 may be provided with a sensor for sensing whether the cluster interface is connected to the pipeline to be cleaned. When the cluster interface 311 is connected to multiple pipelines to be cleaned of the device to be cleaned, the control module may control the one-way valve to be turned on, and control the first drive member M1 to switch to a working state, so as to allow cleaning agents and water to flow to the pipeline to be cleaned through the cluster interface, thereby reducing the operation of manually switching the one-way valve state, and realizing automatic cleaning of the pipeline to be cleaned to a certain extent.

[0048] Optionally, one end of the second tube group 33 used for connecting with the pipeline to be cleaned may be provided with a quick-connect interface, and connected to the pipeline to be cleaned through the quick-connect interface, thereby improving the assembly efficiency of both the pipeline to be cleaned and the cleaning device.

[0049] In an alternative embodiment, if Figure 2 As shown in the example, Figure 2 It is a structural schematic diagram of another embodiment of the cleaning device of the present application. The first pipe group includes a cluster interface 311, which is used to connect to multiple pipelines to be cleaned of the device to be cleaned; the drive group 32 includes multiple peristaltic pumps M2, and the peristaltic pumps M2 are respectively arranged in each pipeline to be cleaned. For example, automated catering equipment such as automatic milk tea machines can usually be provided with peristaltic pumps in their liquid delivery pipelines. In this embodiment, when the pipeline to be cleaned has a peristaltic pump M2, it is used to provide power.

[0050] Please continue reading Figure 1 In one embodiment, the first tube group 31 may be provided with a first switch 34, which is provided between the driving group 32 and the water containing chamber 11, and is used to open or close the passage of the first tube group 31. When the first switch 34 is on, the liquid discharged from the device to be cleaned can flow back to the water containing chamber 11 through the first tube group 31; when the first switch 34 is off, the liquid is not allowed to flow back to the water containing chamber 11 through the first tube group 31, that is, the cleaning agent and water discharged from the device to be cleaned are not allowed to flow back to the water containing chamber 11 through the first tube group 31.

[0051] Optionally, the first switch member 34 may be a stop valve, a ball valve, etc., which is not limited here.

[0052] Please continue reading Figure 1 In one embodiment, the pipeline assembly includes a third pipe group 35 and a fourth pipe group 36, the third pipe group 35 is connected to an external water source, and the fourth pipe group 36 is connected to the outside.

[0053] The cleaning device may further include a selection switch element and a second switch element 37 .

[0054] The second switch element 37 is disposed on the third tube assembly 35 , so as to control whether water is allowed to be injected into the water containing chamber 11 by turning on or off the second switch element 37 .

[0055] The selection switch can selectively conduct the first tube group 31 or the fourth tube group 36 to allow the cleaning agent and water to flow back to the water chamber 11 or be discharged to the outside of the cleaning device. In detail, when the selection switch conducts the passage between the first tube group 31 and the pipeline to be cleaned, the cleaning agent and water flowing out of the pipeline to be cleaned are allowed to flow back to the water chamber 11; when the selection switch conducts the fourth tube group 36, the cleaning agent and water flowing out of the pipeline to be cleaned are allowed to be discharged from the cleaning device.

[0056] Optionally, the selective switch element may be a three-way valve, a plurality of switch elements, etc., which is not limited here.

[0057] Please continue reading Figure 1 In one embodiment, the selection switch may include a third switch 38 and a first switch 34. The first switch 34 may be disposed in the first tube set 31 as described above; the third switch 38 may be disposed in the fourth tube set 36. Thus, when the first switch 34 conducts to the first tube set 14, the cleaning agent and water are allowed to flow back to the water chamber 11; when the third switch 38 conducts, the cleaning agent and water are discharged.

[0058] Optionally, in an alternative embodiment, the fourth tube set 36 may be connected to the bottom of the water chamber 11 and may extend in a direction away from the water chamber 11. In other words, when the cleaning device is properly placed, the fourth tube set 36 is connected to the bottom of the water chamber 11 and extends in the direction of gravity. In this way, the present embodiment may omit power structures such as a water pump to a certain extent, and when it is necessary to remove the liquid in the water chamber, the liquid in the water chamber may be removed from the fourth tube set 36 by gravity.

[0059] In conjunction with the above-described embodiment of the pipeline assembly 30 including the first switch member 34 and the first pipe group 31, please continue to refer to Figure 1 .

[0060] In one embodiment, the connection point between the first tube group 31 and the third tube group 35 is a first connection point A, and the connection point between the first tube group 31 and the fourth tube group 36 is a second connection point B.

[0061] The first switch 34 of the first tube group 31 may be disposed between the first connection point A and the second connection point B. The first connection point A is the connection point between the first tube group 31 and the third tube group 35, and the second connection point B is the connection point between the first tube group 31 and the fourth tube group 36; the second switch 37 is disposed on the side of the first connection point A away from the first switch 34; and the third switch 38 is disposed on the side of the second connection point B away from the first switch 34.

[0062] Optionally, the second switch element 37 and / or the third switch element 38 may be a stop valve, a ball valve, etc., which is not limited here.

[0063] The working principles of the first switch element 34 , the second switch element 37 and the third switch element 38 are described below by way of example.

[0064] like Figure 1 As shown in the example, when water needs to be injected into the water containing chamber 11, the second switch 37 can be controlled to be turned on, and the first switch 34 and the third switch 38 can be turned off. Water from the external water source flows into the third tube group 35 through the water inlet of the third tube group 35, flows into the first tube group 31 through the first connection point A, and since the first switch 34 is turned off, the injected water can flow into the water containing chamber 11.

[0065] When the pipeline to be cleaned is circulated and cleaned with liquids such as descaling agents, detergents, water, etc., the first switch 34 is controlled to be turned on, and the second switch 37 and the third switch 38 are turned off. The cleaning agent in the storage component 20 can flow to the water containing chamber 11 through the discharge port 22 and mix with water to form a mixed liquid. Using the power provided by the drive group 32, the mixed liquid / water is sequentially extended into one end of the water containing chamber 11 through the second tube group 33, and flows to the pipeline to be cleaned through the quick-connect interface of the second tube group 33 connected to the pipeline to be cleaned. After passing through the pipeline to be cleaned, it passes through the cluster interface 311, the first tube group 31 and the first switch 34 in turn to flow back to the water containing chamber 11.

[0066] When the circulation cleaning of the pipeline to be cleaned by liquids such as descaling agent, detergent, water, etc. is completed, the third switch 38 is controlled to be turned on, and the first switch 34 and the second switch 37 are turned off, so that the mixed liquid / water in the water chamber 11 passes through the second tube group 33, the pipeline to be cleaned, the cluster interface 311, the partial section of the first tube group 31 and the fourth tube group 36 in sequence to be discharged to the outside of the cleaning device.

[0067] Please continue reading Figure 1 In one embodiment, a liquid level sensor 40 is provided in the water chamber 11 for sensing the liquid level in the water chamber 11 , so that the liquid level is detected during the process of filling, draining, and circulating cleaning the water chamber 11 , and water is replenished, drained, etc. are drained when necessary according to the liquid level sensed by the liquid level sensor 40 .

[0068] See also Figure 3 , Figure 3 It is a structural schematic diagram of an embodiment of a beverage preparation system of the present application.

[0069] In one embodiment, the beverage preparation system includes a beverage preparation device 500 and a cleaning device 100 . The cleaning device 100 can be detachably connected to the beverage preparation device 500 .

[0070] As the name implies, the beverage preparation device 500 can prepare beverages such as milk tea, juice, etc. The beverage preparation device 500 can include a juice dispenser, a liquid flow pipeline, etc., which are not limited here.

[0071] The cleaning device 100 is a device that can clean the device 100 to be cleaned. In this embodiment, the beverage preparation device 500 can be used as the device 100 to be cleaned.

[0072] The beverage preparation device 500 and the cleaning device 100 are detachably connected, which is conducive to enriching the application scenarios of the cleaning device 100 and also conducive to reducing the volume of the beverage preparation system when the beverage preparation device 500 does not need to be cleaned. In other words, when the beverage preparation device 500 is in normal working state such as preparing beverages, the beverage preparation device 500 does not need to be connected to the cleaning device 100. When the beverage preparation device 500 needs to be cleaned, the cleaning device 100 is assembled and connected with the beverage preparation device 500.

[0073] For the specific limitations of the cleaning device, please refer to the limitations on the composition structure and working principle of the cleaning device in the previous article, which will not be repeated here.

[0074] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
